Qiagen TB blood test gets thumbs up in Nigeria

Nigeria is the first high-burden country to exclusively embrace interferon gamma release assays (IGRAs) for latent TB screening of at-risk individuals in tuberculosis control programs, Qiagen noted. The national guidelines are based on World Health Organization (WHO) recommendations for screening, and including IGRA tests will help avoid progression to active TB, Dr. Adebola Lawanson, national coordinator of the TB program at the Nigeria Federal Ministry of Health, said in a statement from the company.

Which eligible gene signatures make the grade for TB blood tests?

The review evaluated whole blood mRNA signatures that have been proposed for identifying the onset of TB. The authors used a patient-level pooled dataset of four studies that included 1,126 samples from 905 patients, with 183 samples from 127 cases of incipient tuberculosis, which is defined as the asymptomatic phase of disease. The dataset included cases from African countries -- South Africa, Ethiopia, and Gambia -- and the U.K.

NIH funds creation of granuloma lab model for TB and HIV

Texas Biomed has a two-year study grant to create a model for granulomas, which are masses of macrophages, lymphocytes, and other cells that form in response to an infection with Mycobacterium tuberculosis. In people infected with HIV and TB, HIV is present in granulomas. The interaction is complex, and animal models haven't been up to the task of evaluation, Texas Biomed said in a statement.
